The classical preload design method of prestressed frame of hydraulic presses is based on the assumption that the beams of the frame are rigid, which is not agree with practice. In order to eliminate the unbalance load of the frame of a 100MN hydraulic press due to improper prestressing, tie rod preload distribution in prestressing of the frame is researched with respectively mechanics of materials and the finite element methods. According to mechanics of materials and finite element analysis results, reasonable tie rod preloads and sequence of preloading are obtained and the unbalance load of the frame of the hydraulic press is solved. It also provides references for the preload design of prestressed frame of hydraulic presses.

In order to satisfy the needs of small hydraulic press enterprises, a case-based reasoning design method is proposed, which introduces the techniques of parametric design, finite element analysis and optimization. The parametric CAD design system for small hydraulic press is developed based on SolidWorks by using VC++. And this system is composed of parametric design, database, finite element analysis and optimization. Customers’ feedbacks show that the parametric CAD design system has greatly enhanced the efficiency of the design.

A method of structural optimization for upper beam is proposed in order to satisfy the requirements of high stiffness and light weight of isothermal hydraulic press. Finite element analysis mold is established in ABAQUS by analyzing structural features and load conditions of hydraulic press. When original structure is retained, stiffness and strength of upper beam are checked based on finite element analysis mold. Key factors influencing stiffness and mass are extracted and analysis results are obtained by experiment design. Mathematical model for structural optimization is established by second order stepwise regression model. The goal of structural optimization is to increase stiffness of upper beam while mass is set as constraint. The stiffness of upper beam is increased by 7.04% and its mass remains unchanged basically when structural optimization is finished.
